The amount of points lost by entering the bonus stages is minimal, you can even wait that fire is almost catching you before entering a door, if you want to extend the leeching. You risk of course that the door doesn't bring to a bonus stage then, and you have to escape from fire rapidly.

The real last weapon can't be achieved with green-alien-powerups because (for a glitch? or was it intended?) they don't release the power up after a certain point. Bonus stages instead make your gun go up of some levels anyhow, though.

it's been set to 4-way for the next release.. the bug is confirmed to happen on the pcb, but it's most likely the original cab used 4-way joysticks so it never actually occurred. (a bit like how you can reboot one of the metal slug games by pressing left+right at the same time if we allow that)
